The goal of this observational study is to learn about dietary quality and barriers to healthy eating among older adults who participate in the Los Angeles County Food Rx Produce Distribution Program. The study will also evaluate whether a newer dietary assessment tool, the Global Diet Quality Questionnaire (GDQQ), performs similarly to an established dietary assessment tool, the Mediterranean Diet Scale (PREDIMED MDS), in measuring diet quality among adults aged 60 years and older. The main questions it aims to answer are: * Is the GDQQ associated with diet quality scores measured by the PREDIMED Mediterranean Diet Scale? * Does the GDQQ predict self-reported body mass index (BMI) as well as or better than the PREDIMED Mediterranean Diet Scale? * What barriers and facilitators influence healthy eating and participation in produce distribution programs among older adults? Participants will: * Complete questionnaires about their dietary habits, demographic characteristics, and food access experiences. * Complete two dietary quality assessment tools: the PREDIMED Mediterranean Diet Scale and the Global Diet Quality Questionnaire. * If randomly selected, participate in a one-time semi-structured interview to discuss healthy eating, food access, experiences with produce distribution events, and challenges to improving dietary quality.

Capsimax is a novel, proprietary encapsulated form of capsaicin, a natural and bioactive phytochemical found in chili pepper and other spicy food. The purpose of this study is to investigate the effect of Capsimax on resistance exercise performance, reaction time, and resting energy expenditure around exercise. This investigation will also measure muscle oxygenation and intramuscular nitric oxide in real time during resistance exercise using a non-invasive wearable technology. Primary Objective • To examine the effects of Capsimax on physical performance metrics including peak power and rate of force development during an isometric strength test and performance during the barbell back squat exercise protocol (e.g., repetitions performed, total volume, peak power, average power). Secondary Objectives * To examine the effects of Capsimax on resting energy expenditure around exercise. * To examine the effects of Capsimax on nitric oxide bioavailability and skeletal muscle oxygenation during exercise. Exploratory Objective • To examine the effects of Capsimax on reaction time around exercise
